Tariff-rate quotas (TRQs or tariff quotas) are predetermined quantities of goods which can be imported at a "preferential" (i.e. lower) rate of customs duty ("in quota tariff rate"). Once the TRQ has been filled, one can continue to import the product without limitation but paying a higher tariff rate.
TRQs are applicable only to Agriculture products and included in schedules concessions and commitments under the WTO.
